Switching regulator subsystems intended for use asdc to dc converters. 3V to 40 Volt DC Converter circuit | The use of switching regulators is becoming more pronounced over that of linear regulators because the size reductions in new equipment designs require greater conversion efficiency. Another major advantage of the switching regulator is that it has increasednapplication flexibility of output voltage. The output can be less than, greater than, or of opposite polarity to that of the input voltage.
The MC34063 series is a monolithic control circuit containing all the active functions required for dc to dcconverters. This device contains an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active peak current limit circuit, driver, and a high current output switch. This series was specifically designed to be incorporated in step–up, step–down and voltage–inverting converter applications. These functions are contained in an 8–pin dual in–line package.
